The silencing mechanism 200 includes an adjustment assembly 210 and a silencing assembly 230. Wherein, the sound-deadening assembly 230 includes a sound-deadening plate 231 and a supporting member 233, and the adjusting assembly 210 is connected to the sound-deadening assembly 230 and the concrete isolation layer 150, respectively. A cavity 300 is enclosed between the sound attenuating element 230 and the concrete barrier 150.

The adjusting component 210 is respectively connected with the silencing component 230 and the concrete isolation layer 150, so that a cavity 300 is enclosed between the silencing component 230 and the concrete isolation layer 150, noise conducted by air is weakened, and the vibration isolation and silencing floating building system 10 has a better silencing effect.

Referring to fig. 1 and 2, in one embodiment, the vibration isolation assembly 100 further includes a noise reduction layer 170, and the noise reduction layer 170 is attached to the concrete isolation layer 150. In this embodiment, the buffering noise reduction layer 170 is attached to the concrete isolation layer 150, so that the concrete isolation layer 150 better supports the buffering noise reduction layer 170, and the buffering noise reduction layer 170 can better reduce noise. Further, the buffering noise reduction layer 170 is sticky with the concrete isolation layer 150, the vibration isolation and noise reduction sealing performance is improved, the noise reduction effect of the vibration isolation and noise reduction floating construction system 10 is further enhanced, the compression buffering noise reduction layer 170 and the thickness of the concrete isolation layer 150 in a fit mode are compressed, and a certain layer space is reserved. Further, the noise reduction and buffering layer 170 abuts against the surface of the filling member 133 away from the concrete facing layer 110, so that noise is damped simultaneously through the filling member 133 and the noise reduction and buffering layer 170. It should be noted that the buffering noise reduction layer 170 is a recyclable environment-friendly material, is formed by mixing polyurethane and cork, and has good heat insulation performance, physical performance and mechanical performance. Specifically, the dynamic performance of the noise reduction layer 170 is greater than or equal to 27MN/m ^3, and the tensile strength of the noise reduction layer 170 is greater than 100KPa, so that the noise reduction layer 170 has good ductility, and the noise reduction layer 170 better blocks the noise generated by impact. In one embodiment, the thickness of the noise reduction layer 170 is 6mm, and after pressure impact, the recovery speed and performance of the noise reduction layer 170 are better, and through acoustic testing, the impact sound insulation grade of the noise reduction layer 170 is 51dB, and the impact sound insulation improvement of the noise reduction layer 170 is 20 dB.

It is understood that in other embodiments, the buffering and noise reducing layer may be omitted, and the buffering and vibration reducing block is directly abutted to the concrete isolation layer, so that the vibration reducing layer acts between the concrete isolation layer and the concrete facing layer.

In one embodiment, referring to fig. 1 and fig. 4, the buffering and vibration-damping blocks 131 are arranged on a side of the buffering and noise-reducing layer 170 away from the concrete isolation layer 150, so that the buffering and vibration-damping blocks 131 abut against the concrete isolation layer 150 through the buffering and noise-reducing layer 170, and the vibration-isolating, noise-reducing and floating system 10 has a better vibration-damping effect. In this embodiment, the quantity of buffering damping piece 131 is a plurality of, and a plurality of buffering damping piece 131 are array and arrange, make vibration isolation amortization float build system 10 have better damping effect for buffering damping piece 131 installs convenient more nimble, and then can be applicable to indoor not unidimensional area space, possesses good practicality. Further, the plurality of damping blocks 131 are arranged in an array on the side of the noise reduction layer 170 away from the concrete isolation layer 150, and the length-width ratio between the array of the plurality of damping blocks 131 is as long: width is 3: 2.

Further, each damping block 131 is square, so that the damping blocks 131 have buffering and damping functions in the vertical direction, the bearing performance of the damping blocks 131 is more stable, the deformation resistance of the damping blocks 131 is improved, and the service life of the damping blocks 131 is prolonged. In the present embodiment, each of the damping blocks 131 is a cube having a size of 50mm × 50mm × 50mm, and the contact surface between each of the damping blocks 131 and the noise reduction layer 170 is more stable, so that the damping blocks 131 have the same sound insulation and vibration reduction effects. It is to be understood that in other embodiments, each of the damper blocks 131 is not limited to a square shape, and for example, each of the damper blocks may also have a cylindrical shape, a straight triangular prism shape, a circular truncated cone shape, or the like.

In the embodiment, the material of the damping mass 131 is a vibration control recyclable material, for example, the damping mass 131 is formed by mixing cork and natural rubber, so that the total load of the damping mass 131 reaches 2.0MPa, the static pressure range is 0.40 to 1.50MPa, and the elongation at tear is greater than 300, and further the damping mass 131 has a certain tensile strength and tear strength, and the damping mass 131 has high damping performance, and the dynamic-static stiffness ratio can reach 2 to 5, so that the damping mass 131 has long-term durability, and the damping mass 131 generates a low amplitude when resonating.

The conventional vibration isolation assembly 100 has a poor noise reduction effect at high temperature, and in one embodiment, the temperature range of the buffering vibration attenuation block 131 is-10 to 100 ℃, so that the vibration isolation performance of the vibration isolation assembly 100 in a high-temperature environment is ensured.

In one embodiment, it can be understood that when the thickness of the concrete finishing layer 110 is too thick, the concrete finishing layer easily occupies too much interior space, and exceeds the bearing force of the damping block 131, and the damping block 131 is easily damaged to some extent. When the thickness of the concrete finishing layer 110 is too small, the required vibration isolation effect is not easy to be realized, in the embodiment, the thickness of the concrete finishing layer 110 is 100mm, so that the thickness of the concrete finishing layer 110 is moderate, meanwhile, the buffer vibration-damping block 131 is prevented from being damaged, and more indoor decoration spaces are further reserved.

Referring to fig. 1 and 3, in one embodiment, the filling member 133 is provided with a mounting hole 1331, the damping block 131 is inserted into the mounting hole 1331 and abuts against the filling member 133, and the filling member 133 is located between the concrete finishing layer 110 and the concrete isolation layer 150. Arrange buffering damping piece 131 in mounting hole 1331, and with filler 133 looks butt, make buffering damping piece 131 combine more firm with filler 133, make the vibration of buffering damping piece 131 subdue fast through buffering damping piece 131 simultaneously, the damping efficiency of vibration isolation amortization floating construction system 10 has been improved, make buffering damping piece 131 and filler 133 use non-deformable for a long time, the structural stability of vibration isolation layer 130 has been strengthened, make vibration isolation layer 130 effect more stable in long-term use. Meanwhile, the filling piece 133 is attached to the side, away from the concrete isolation layer 150, of the buffering noise reduction layer 170, and the filling piece 133 is used for blocking transmission of partial noise, so that noise with different indoor frequencies is greatly reduced.

In one embodiment, the damping block 131 is in interference fit with the mounting hole 1331 of the filler 133, so that noise is effectively transmitted to the filler 133 through the damping block 131 for damping, and the damping effect of the vibration isolation and noise reduction floating building system 10 is improved. In the present embodiment, the damping block 131 is a cube structure, and the mounting hole 1331 is adapted to the damping block 131, so that the damping block 131 has a good damping effect in all directions. It can be understood that, considering the manufacturing precision deviation of the damping mass 131 and the mounting hole 1331 of the filling member 133, there may be a gap between each damping mass 131 and the corresponding mounting hole 1331, so that the effect of further damping the noise transmitted to the filling member 133 after the noise is damped by the damping mass 131 is poor, further, the vibration isolation and noise reduction floating system 10 further comprises an elastic band which is wrapped on the periphery of the damping mass 131 and elastically abuts between the filling member 133 and the damping mass 131, so that the noise is effectively transmitted to the filling member 133 through the damping mass 131 for damping, and the requirement of the processing precision of the damping mass 131 and the inner wall of the mounting hole 1331 is reduced. In this embodiment, a plurality of sound reducing holes are formed in the elastic band, and the plurality of sound reducing holes are uniformly distributed on the surface of the elastic band, so that the elastic band has a good vibration reduction effect. Further, the elastic band is of a sleeve band-shaped structure, so that the elastic band has a larger contact area with the filling piece 133 and the buffer damping block 131, and the elastic band has a better damping effect. Of course, in other embodiments, the elastic band may also be spirally wound around the periphery of the damping block, so that noise is effectively transmitted to the filling member 133 through the damping block 131 for damping, and meanwhile, the processing difficulty and the processing cost of the elastic band are reduced.

In order to make the elastic band closely fit between the filling member 133 and the buffering damping block 131, and make the noise better conduct to the filling member through the buffering damping block 131 for damping simultaneously, further, the cross-section of the elastic band in the thickness direction of the filling member is an arc-shaped convex structure, namely the outside of the elastic band departing from the buffering damping block 131 is a curved surface convex structure, when the buffering damping block 131 is installed in the installation hole 1331 through the elastic band, the elastic band extrudes and deforms, so that the elastic band closely fits between the filling member and the buffering damping block, and simultaneously make the noise better conduct to the filling member 133 through the buffering damping block 131 for damping. In order to avoid vibration isolation amortization system 10 of floating building in the use, the elastic webbing receives frequent vibration to break away from buffering damping piece easily, lead to the problem that the effect that carries out the damping through buffering damping piece 131 conduction to filler 133 weakens, furthermore, the elastic webbing is glued in buffering damping piece 131 surface, make elastic webbing and buffering damping piece 131 fastening connection, avoid vibration isolation amortization system 10 of floating building in the use, the elastic webbing receives frequent vibration to break away from buffering damping piece easily, lead to the problem that the effect that carries out the damping through buffering damping piece 131 conduction to filler 133 weakens. Further, a plurality of adhesion positioning grooves are formed in the surface, adjacent to the buffering vibration attenuation block 131, of the elastic band, so that the adhesive area of the surface of the elastic band is large, and the elastic band is further adhered to the surface of the buffering vibration attenuation block 131 better. Furthermore, a plurality of bonding bosses are convexly arranged on the surface of the damping block 131 at intervals, so that the bonding area of the surface of the damping block 131 is larger, and the elastic band is better bonded on the surface of the damping block 131. Furthermore, the surface of the buffering and vibration-damping block 131 is provided with glue containing holes, so that when the elastic band is glued on the surface of the buffering and vibration-damping block 131, part of glue enters the glue containing holes for curing, and the elastic band is bonded with the buffering and vibration-damping block 131 more firmly. Further, the glue containing hole is of an inclined hole structure, so that the elastic band can be better glued on the surface of the buffering and vibration damping block 131.

It is understood that in other embodiments, the elastic band may be omitted, and the mounting holes 1331 of the damper mass 131 and the filler member 133 are not limited to interference fit. In order to tightly connect the damping block 131 with the mounting hole 1331 of the filler 133, further, the damping block 131 is glued into the mounting hole 1331 of the filler 133, so that the damping block 131 is tightly connected with the mounting hole 1331 of the filler 133, noise is effectively transmitted to the filler 133 through the damping block 131 for damping, and the damping effect of the vibration isolation and noise reduction floating building system 10 is improved. Specifically, each buffering and damping block 131 is glued with the buffering and noise-reducing layer 170, so that the buffering and damping block 131 is reliably attached to the buffering and noise-reducing layer 170, and the vibration isolation and silencing floating construction system 10 is simpler in structure.

It should be further noted that, in the present embodiment, the filling member 133 is made of glass wool, so that the filling member 133 has a large number of tiny air pores, so that the filling member 133 has the functions of heat preservation, heat insulation, sound absorption, noise reduction, safety protection, and the like, and meanwhile, the physical property of the filling member 133 is stable, and the filling member also has the antibacterial, mildew-proof, aging-resistant, and corrosion-resistant properties. It is understood that the filling member 133 may be designed into any shape, so that the filling member 133 has better environmental adaptability.

It will be appreciated that the primary factors affecting the sound absorbing properties of the filler 133 are thickness, density and air flow resistance. Of these, air-flow resistance, which refers to the ratio of air pressure and air flow rate on both sides of the material per unit thickness, is the most important factor affecting the sound absorption performance of the filler 133. In practical engineering, it is difficult to measure the air flow resistance, but it can be roughly estimated and controlled by the thickness and volume weight, and as the thickness of the filler 133 increases, the middle and low frequency sound absorption coefficient also increases significantly. When the thickness is unchanged, the volume weight is increased, and the middle and low frequency sound absorption coefficient is also increased; when the volume weight is increased to a certain degree, the material becomes dense, the flow resistance is greater than the optimum flow resistance, and the sound absorption coefficient is rather decreased, in this embodiment, the thickness of the packing member 133 is 25mm, and the volume weight of the packing member 133 is 48kg/m³At the moment, the low-frequency 125Hz position is close to 0.6-0.7, and the sound absorption coefficient of the medium-high frequency (more than 500Hz) is larger than 1, so that the vibration isolation and silencing floating construction system 10 has a better vibration isolation and silencing effect, the thickness of the vibration isolation assembly 100 is effectively controlled, and a sufficient indoor activity space is reserved. Specifically, in the present embodiment, the material of the filling member 133 is centrifugal glass wool, and in other embodiments, the material of the filling member 133 is not limited to centrifugal glass wool, and may be one of ultra-fine glass wool, polyurethane foam, and the like.

In the present embodiment, the supporting members 233 are bonded to the sound-deadening plates 231, respectively, so that two adjacent sound-deadening plates 231 are juxtaposed in parallel and have a combined sound-deadening effect. Further, in this embodiment, the sound-deadening plate 231 is made of a gypsum board, and the gypsum board has a fire-proof function, so that the fire-proof performance of the sound-deadening mechanism 200 is improved. Specifically, the thickness of the gypsum board is 8 mm-15 mm. When the thickness of the gypsum board is 8-15 mm, the noise is better weakened, and the noise reduction effect is improved.

In other embodiments, the acoustical panel 231 further comprises a microporous layer comprising a plurality of acoustical apertures arranged in an array in the microporous layer. The muffling holes are uniformly distributed on the microporous layer in an array arrangement mode, so that the muffling plate effectively weakens low-frequency noise in a microporous muffling mode, improves the muffling performance of the muffling plate, and has a wider application range of the muffling plate 231. In the embodiment, the aperture of the sound-deadening hole 231 is 6mm to 9mm, and when the aperture of the sound-deadening hole 231 is 6mm to 9mm, the low-frequency noise is effectively reduced, and particularly, the noise with the frequency below 120Hz has a better reduction effect.

The two sound-deadening plates 231 are bonded to the support main body 233a so that each sound-deadening plate 231 is connected to the support main body 233a through the corresponding extension 233b, enhancing sound-deadening sealing. It will be appreciated that, in order to ensure a stable connection of the acoustic panel 231 to the support 233, in other embodiments, the support body 233a and the two extensions 233b are integrally formed, ensuring a secure connection of the support body 233a and the two extensions 233 b. In this embodiment, the main body 233a and the two extending portions 233b are integrally formed, so as to improve the structural strength of the supporting member 233, further enhance the connecting strength between the sound-deadening plate 231 and the supporting member 233, effectively simplify the installation process of the sound-deadening assembly 230, and facilitate the stable connection between the sound-deadening assembly 230 and the adjusting assembly 210.

Further, in the present embodiment, each extension 233b also supports the side of the corresponding sound-deadening sheet 231 facing away from the concrete insulating layer 150. The two extension parts 233b protruding from the two sides of the support member main body 233a support the corresponding sound-deadening plates 231, so that the support effect of the support member 233 on the sound-deadening plates 231 is improved, the connection strength of the sound-deadening assembly 230 is improved, and the sound-deadening assembly 230 is further firmly connected with the adjusting assembly 210.
